 In this method, you start with your hand completely open and in an "L" shape. Point your fingers in the direction of $\vec{A}$, then curl your fingers toward the direction of $\vec{B}$. Whichever way your thumb points is the direction of $\vec{C}$. In this method, you start with your hand completely open and in an "L" shape.

 +====Method 3 - Shortcut for Magnetism====
 +
 +In this method, you start by pointing your thumb in the direction of the velocity of a point charge, then you curl your fingers. $\vec{B}$ will point in directions tangent to the circle your fingers make as they curl. This works for a positive charge, if the charge is negative, flip your hand and point your thumb in the direction of $-\vec{v}$ instead.
